Where to Send Motion of Discovery for Chp Speeding Ticket

My question involves a traffic ticket from the state of: California
Hello, can anyone confirm to me where I send my motion of discovery if I was ticketed by the CHP and the Supreme Court of California in Ventura County is handling the case?
CHP Ventura office?
The court?
District attorney? (seems to be in the same building)
Thank you for the help.
